I guess some of us confuse "stuff" with "ability to strike guys out". I know I do, when I say a guy doesn't have stuff, I don't mean he can't throw 94 MPH, I mean his pitching repertoire does not seem to create easy outs. Johnson has pitched 431 AAA innings and has a K/9 rate of 5.9/9 ip, his K/BB rate is well under the magic 2.00 line. For reference Pedro Hernandez (in a smaller sample size) at AAA: 6.2/3.09, and we saw how that worked out for the Twins. It's very rare for a guy with this long of a questionable AAA track record to get magically better in the majors. It's just more of the same. We can trash the viability of Welker all we want, and perhaps for merit, but I just don't see anything in Johnson's past to indicate he has the "stuff" to be a competent major league starter. Unless he has developed a knuckle ball it just ain't happening unless he gets extremely lucky, and that labels him as more of the same to me.
